【Abstract】 Desulphurization techniques have found applications since 1970s, and a considerable variety of techniques have been developed up to date. It is of great importance to the application of desulphurization techniques to large- and medium-capacity boilers that the operating costs for desulphurization need to be reduced. This paper described a desulphurization technique by use of alkaline substances contained in the cinder and bleed water from coal-fired boilers. In addition, the effects on the dissolving ratio of alkaline substances contained in the cinder were investigated, and the desulphurization mechanism was discussed. It was concluded that this technique can reduce the operating costs for desulphurization significantly by use of wastes from boilers.更多还原
